To allwhom it may concern:

1 Be it known that we, FREDERICK C. FLEM- ING and FRANK Roon, citizens of the United States, and residents Vof the city of Chicago,

county of Cook, and State of Illinois, have invented certain new and useful Improvements in Driers, of which the following is a Our invention relates to driers employed in the draining of fertilizer, sand, etc. @l

The object of our invention is the provision of a drum or shell for a drier of the character mentioned which shall be of new and improved construction, which will conduce to strength and durability, and one which will be of highest efficiency in operation.

Other objects will appear hereinafter.

With'these objects in view our invention consists in a drum for driers characterized as above mentioned and in certain details of construction and arrangement of parts all as will be hereinafter .more fully described and particularly pointed out in the appended claims. p

Our invention will be more readily understood byreference 4to the Iaccompanying drawings forming a. part of this specification and in which,

Figure lis a side elevation partially in section of a drier embodying our invention, and Fig. 2 is a transverse section taken on;` substantial line of Fig. 1.

Referring now to the drawings 1 indicates y a suitable base member or mounting upon which is supported a horizontally disposed cylindrical drum or shell, the latter being rigidly secured to said base member since in operation the same is designed to remain stationary. In operation, the ends of said frame are provided lwith heads suitably secured thereto, agitating devices having bearings in said heads being rotated within said drum to effect the agitation of the contents of the latter and so as toifacilitate a more thorough desiccation thereof. Said agitating devices and heads are however not shown, since the invention is embodied entirely in the construction of the\ d,rum of the drier and which drumis shown in detail in the drawings. As illustrated in tlie drawings said drum comprises an outer met-allie wall or cylinder 2 and an inner coaxia'lly arranged wall or cylinder 3, said inner cyindervbeing of less diameter than said. oute cylinder so that an annular steam acket 4 is formed be- Speciication of Letters Patent.

tween the same, Said cylinders are each of a sectional nature, the cylinder 2 being formed of two semi-cylindrical sections having overlapping edges which are rigidly secured together as at 5 preferably by riveting. The cylinder 3 is also formed preferably of two small cylindrical sections the contiguous longitudinal edges of which are rigidly secured together by means of longitudinally extending plates which are rigidly secured to "said edges as at 6 preferably by means of rivets. Said cylinders are held in coaxial or 'spaced relation Aby Vmeans lof metallic rings 7 which arefarra'iiged at the ends and between the adjacent ysurfaces thereof, said rings being secured in position by means of rivets 8 which pass therethrough and through the adjacent ends of said cylinders, as clearly shown in Fig. 1. At the upper side of the cylinder 2 adjacent the respective extremities v thereof are provided steam inlet ports 9 and at the under side of saidcylinder also adjacent the extremities thereof are provided steam outlet ports 10, said ports 9 and 10 communicating with the steam jacket 4. In order to provide for the connection of steam supply voutlet pipeflanges 9 and 10 are arranged as indicated at the ports 9 and 10 respectively. f y

Arranged upoii'the outer side of the inner cylinder 3 are spaced ciroumferentially metallic reinforcing rings 11. Said rings are, as clearly shown inv Fig'. 2, of a sectional nature each being comprised of two semi- Circular sections the contiguous angularly projectingends 12 of which are adjustably secured ltogether by means of bolts and nuts 13, such provision being made in order that said rings will be adapted to adjust lthemselves to changes in the circumference of the cylinder 3 because of thevarying diameters thereof when in operation; Said rings 11 are secured at intervals to the cylinder 3 by means of rivets 14, the inner heads of the latter being counter-sunk in the inner surfaces .of said cylinder so that the same will not be exposed to undue or excessive wear. The portion of said ring between adjacent rivets 14 are cut away as at 15 adjacent the upper surfaces of said cylinder 3 "so that a maximum extent of surface will be exposed tothe action of the steam.

A drum for driers of the construction as I vkscribed without departin thepreferred form of our drum' we do not wish to be limited thereto as there might be various chan es made in the details 0f construction `an arrangement of parts de from the spirit of the inventionka's compre ended within the `scope of the ap ended claims.

i ing said inner wall and securedat intervals thereto by means of securing devices extending through said rings and said inner wall, the inner ends of sald securing devices being upset and counter-sunk in said inner wall, substantially as described.

In a drier of the class described, a drum comprising. coaxial inner and outer cylinders of di erent diameters forming a steam jacket about said inner cylinder, spacin rings at the ends of said cylindersto whic the latter are ri 'dly secured and circumferentially exten ing reinforcing rin s upon the outer surface of said inner c liner and securely riveted tothe latter, t e securin p' rivets extending through said rings and sai inner cylinder, the inner heads of said rivets being counter-sunk in the inner surfaces of' said inner cylinder, substantially as described.

4. In a drier of the class described, a drum'y comprising coaxial inner and outer cylinders of different diameters forming a steam jacket aboutsaid inner cylinder, spacing rings at the ends of said cylinders to which the latter are. rigidly secured, circumerentially extending reinforcing rings upon the outer surface of said inner cylinder and securin rivets to the latter, the securing rivets o said rings extending through the latter and said inner cylinder, the inner heads of said rivets bein counter-sunk in the inner surfaces of said inner cylinder, the portion of said rings .intermediate adjacent rivets and' adjacent the outer surface of said cylinder being cut away, substantially as described.

5. In a drier ofthe class described, a drum comprising two coaxial cylinders or" diderent diameters forming a steam jacket around the inner cylinder, metallic spacing rings at the ends of said cylinders to which the latterairs-n` rigidly secured, circumi'erentiaily extending sectional metallic rings upon the outer surface of said inner cylinder and securely riveted to the latter, said last mentioned rings being of Vless Width than said steam jacket, the securing rivets of said rings extending through the latter and said inner cylinder, the inner heads of said rivets being counter-sunk in the inner surface of said inner cylinder, and the portion of said rings intermediate adja cent rivets and adjacent the outer surfaces of said inner cylinder being out away, substantially as described.

In testimonywhereot we have signed our names to this specification in the presence ot two subscribing witnesses.
